All jewel thief Miles Logan (Martin Lawrence) wants to do is make the score of his life and live like a fugitive king at a faraway Mexican retreat. But the fast-talking Logan barely escapes with his life when his carefully planned heist of a $20 million diamond goes awry. Double-crossed by Deacon (Peter Greene), a greedy member of his crew, Miles makes a daring escape to a nearby building under construction, unaware it's a new precinct for the Los Angeles Police Department where he hides the gem before the cops catch him. Released from prison two years later, Miles poses as LAPD "Detective Malone," while looking for the diamond hidden in an air vent in the men's room. Inadvertently he captures an escaping suspect and impresses Captain Rizzo (Graham Beckel), who promotes Miles to partner with Carlson (Luke Wilson), a rookie detective. Things get even more complicated for Miles when his former bumbling partner in crime, Tulley (David Chappelle), resurfaces for his cut of the action.
